* Issue #28148: Stop using localtime() and gmtime() in the time module.Alexander Belopolsky2016-09-281-0/+8
| | | | | | Introduced platform independent _PyTime_localtime API that is similar to POSIX localtime_r, but available on all platforms. Patch by Ed Schouten.

* Issue #25155: Add _PyTime_AsTimevalTime_t() functionVictor Stinner2015-09-181-0/+12
| | | | | | | | | | | | | | On Windows, the tv_sec field of the timeval structure has the type C long, whereas it has the type C time_t on all other platforms. A C long has a size of 32 bits (signed inter, 1 bit for the sign, 31 bits for the value) which is not enough to store an Epoch timestamp after the year 2038. Add the _PyTime_AsTimevalTime_t() function written for datetime.datetime.now(): convert a _PyTime_t timestamp to a (secs, us) tuple where secs type is time_t. It allows to support dates after the year 2038 on Windows. Enhance also _PyTime_AsTimeval_impl() to detect overflow on the number of seconds when rounding the number of microseconds.

* Issue #23517: fromtimestamp() and utcfromtimestamp() methods ofVictor Stinner2015-09-091-4/+5
| | | | | | | | | | | | datetime.datetime now round microseconds to nearest with ties going to nearest even integer (ROUND_HALF_EVEN), as round(float), instead of rounding towards -Infinity (ROUND_FLOOR). pytime API: replace _PyTime_ROUND_HALF_UP with _PyTime_ROUND_HALF_EVEN. Fix also _PyTime_Divide() for negative numbers. _PyTime_AsTimeval_impl() now reuses _PyTime_Divide() instead of reimplementing rounding modes.
* Issue #23517: datetime.timedelta constructor now rounds microseconds to nearestVictor Stinner2015-09-021-0/+4
| | | | | | with ties going away from zero (ROUND_HALF_UP), as Python 2 and Python older than 3.3, instead of rounding to nearest with ties going to nearest even integer (ROUND_HALF_EVEN).

* Issue #22117: Add a new _PyTime_FromSeconds() functionVictor Stinner2015-04-031-1/+4
| | | | | Fix also _Py_InitializeEx_Private(): initialize time before initializing import, import_init() uses the _PyTime API (for thread locks).

| | | | Add also more tests for ROUNd_FLOOR.
* Issue #22117: Fix usage of _PyTime_AsTimeval()Victor Stinner2015-03-301-1/+7
| | | | | Add _PyTime_AsTimeval_noraise() function. Call it when it's not possible (or not useful) to raise a Python exception on overflow.

| | | | | | | | | Add also a new _PyTime_AsMicroseconds() function. threading.TIMEOUT_MAX is now be smaller: only 292 years instead of 292,271 years on 64-bit system for example. Sorry, your threads will hang a *little bit* shorter. Call me if you want to ensure that your locks wait longer, I can share some tricks with you.

| | | | | | | | | | | | | | | | | | | | | | | | | | In practice, _PyTime_t is a number of nanoseconds. Its C type is a 64-bit signed number. It's integer value is in the range [-2^63; 2^63-1]. In seconds, the range is around [-292 years; +292 years]. In term of Epoch timestamp (1970-01-01), it can store a date between 1677-09-21 and 2262-04-11. The API has a resolution of 1 nanosecond and use integer number. With a resolution on 1 nanosecond, 64-bit IEEE 754 floating point numbers loose precision after 194 days. It's not the case with this API. The drawback is overflow for values outside [-2^63; 2^63-1], but these values are unlikely for most Python modules, except of the datetime module. New functions: - _PyTime_GetMonotonicClock() - _PyTime_FromObject() - _PyTime_AsMilliseconds() - _PyTime_AsTimeval() This change uses these new functions in time.sleep() to avoid rounding issues. The new API will be extended step by step, and the old API will be removed step by step. Currently, some code is duplicated just to be able to move incrementally, instead of pushing a large change at once.
* Issue #23646: Enhance precision of time.sleep() and socket timeout whenVictor Stinner2015-03-201-7/+5
| | | | | | | | interrupted by a signal Add a new _PyTime_AddDouble() function and remove _PyTime_ADD_SECONDS() macro. The _PyTime_ADD_SECONDS only supported an integer number of seconds, the _PyTime_AddDouble() has subsecond resolution.
* Issue #22043: time.monotonic() is now always availableVictor Stinner2014-09-021-0/+18
| | | | | threading.Lock.acquire(), threading.RLock.acquire() and socket operations now use a monotonic clock, instead of the system clock, when a timeout is used.
* pytime.h: remove duplicated "#ifndef Py_LIMITED_API"Victor Stinner2014-08-311-3/+0
|
* Issue #22043: _PyTime_Init() now checks if the system clock works.Victor Stinner2014-08-291-6/+7
| | | | | | | | | Other changes: * The whole _PyTime API is private (not defined if Py_LIMITED_API is set) * _PyTime_gettimeofday_info() also returns -1 on error * Simplify PyTime_gettimeofday(): only use clock_gettime(CLOCK_REALTIME) or gettimeofday() on UNIX. Don't fallback to ftime() or time() anymore.
* Issue #20320: select.select() and select.kqueue.control() now round the timeoutVictor Stinner2014-02-171-3/+14
| | | | | | aways from zero, instead of rounding towards zero. It should make test_asyncio more reliable, especially test_timeout_rounding() test.
* PEP 418: Rename adjusted attribute to adjustable in time.get_clock_info() resultVictor Stinner2012-06-121-1/+1
| | | | | | | | Fix also its value on Windows and Linux according to its documentation: "adjustable" indicates if the clock *can be* adjusted, not if it is or was adjusted. In most cases, it is not possible to indicate if a clock is or was adjusted.
* Issue #14127: Add ns= parameter to utime, futimes, and lutimes.Larry Hastings2012-05-031-0/+4
| | | | | | Removed futimens as it is now redundant. Changed shutil.copystat to use st_atime_ns and st_mtime_ns from os.stat and ns= parameter to utime--it once again preserves exact metadata on Linux!

* Issue #14428, #14397: Implement the PEP 418Victor Stinner2012-04-291-0/+14
| | | | | | | | | * Rename time.steady() to time.monotonic() * On Windows, time.monotonic() uses GetTickCount/GetTickCount64() instead of QueryPerformanceCounter() * time.monotonic() uses CLOCK_HIGHRES if available * Add time.get_clock_info(), time.perf_counter() and time.process_time() functions
* Issue #14127: Add st_{cma}time_ns fields to os.stat() result object.Larry Hastings2012-04-191-0/+4

* Close #14180: Factorize code to convert a number of seconds to time_t, ↵Victor Stinner2012-03-131-2/+15
| | | | | | | | | | | | | timeval or timespec time.ctime(), gmtime(), time.localtime(), datetime.date.fromtimestamp(), datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp() now raises an OverflowError, instead of a ValueError, if the timestamp does not fit in time_t. datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp() now round microseconds towards zero instead of rounding to nearest with ties going away from zero.
* Issue #13964: signal.sigtimedwait() timeout is now a float instead of a tupleVictor Stinner2012-03-021-0/+11
| | | | Add a private API to convert an int or float to a C timespec structure.

* Issue #9090: When a socket with a timeout fails with EWOULDBLOCK or EAGAIN,Antoine Pitrou2010-09-281-0/+11
| | | | | | retry the select() loop instead of bailing out. This is because select() can incorrectly report a socket as ready for reading (for example, if it received some data with an invalid checksum).
* De-duplicate contents of pytime.hAntoine Pitrou2010-08-131-35/+0

* Issue #9079: Added _PyTime_gettimeofday(_PyTime_timeval *tp) to C APIAlexander Belopolsky2010-08-051-0/+70
exposed in Python.h. This function is similar to POSIX gettimeofday(struct timeval *tp), but available on platforms without gettimeofday().
